  Mr. 
  Van 
  Diizee 
  reports 
  this 
  species 
  as 
  occurring- 
  in 
  Canada, 
  Xew 
  

   England, 
  w^est 
  to 
  Colorado 
  and 
  California. 
  

  

  The 
  only 
  American 
  specimens 
  that 
  1 
  have 
  seen 
  came 
  from 
  the 
  moun- 
  

   tains 
  of 
  Colorado 
  and 
  were 
  taken 
  by 
  Mr. 
  Baker 
  at 
  Steand)oat 
  Springs 
  

   iindby 
  myself 
  at 
  Leadville 
  and 
  on 
  Park 
  Hill, 
  east 
  of 
  Estes 
  Park. 
  The 
  

   specimens 
  taken 
  by 
  Mr. 
  Baker 
  were 
  from 
  willows. 
  

   This 
  species 
  is 
  very 
  close 
  to 
  aureoriridis 
  Uhl. 
  Sm«ra<j(hiht 
  is 
  the 
  

   more 
  slender 
  species 
  and 
  the 
  last 
  ventral 
  segment 
  in 
  

   the 
  female 
  is 
  more 
  strongly 
  produced 
  and 
  sharper 
  

   pointed 
  than 
  in 
  aureoviridis. 
  The 
  latter 
  species 
  is 
  

   also 
  more 
  golden 
  in 
  color 
  and 
  in 
  no 
  case, 
  that 
  I 
  have 
  

   seen, 
  does 
  it 
  have 
  the 
  smoky 
  dorsal 
  line 
  that 
  is 
  so 
  

   common 
  in 
  .stnaragdula. 
  This 
  dark 
  line 
  is 
  not 
  men- 
  

   tioned 
  in 
  the 
  above 
  

   description, 
  but 
  all 
  of 
  

   the 
  twelve 
  specimens 
  

   in 
  my 
  collection 
  from 
  

   Europe 
  have 
  it; 
  less 
  

   than 
  half 
  of 
  those 
  

   from 
  Colorado 
  are 
  so 
  

   marked. 
  

  

  Emj)oaficapi(ra[iitid) 
  

   and 
  ohtusa 
  (Walsh) 
  

   also 
  stand 
  very 
  close 
  

   to 
  tliis 
  S])ecies. 
  

  

  Since 
  writing 
  the 
  

   above 
  1 
  have 
  taken 
  a 
  

   good 
  number 
  of 
  speci- 
  

   mens

  this 
  species, 
  with 
  the 
  dark 
  dorsal 
  stripe 
  very 
  pronounced,

  rivularis

  Cimarron, 
  Colorado,

  22,
